ABSTRACT:
This four stroke V-configuration engine has two cylinder banks which have equal numbers of cylinders, angled with respect to one another at a bank angle .alpha. different from 90.degree.. For each bank of cylinders, the angular positions of the crank shaft crank pins therefor are evenly spaced apart around the central axis of the crank shaft, and between the banks of cylinders the angular positions of a pair of corresponding cylinders are separated by a crank angle of 90.degree.-.alpha.. A first set of balance weights is provided so as to rotate about an axis parallel to the rotational axis of the crank shaft in the same direction and at the same speed as the crank shaft, and a second set of balance weights is provided so as to rotate about an axis parallel to the rotational axis of the crank shaft in the opposite direction and at the same speed as the crank shaft. The positions and the weights of the first and second sets of balance weights are such as to cancel out the first order imbalance moments of reciprocating and of rotational motion.
